PHP：echo wordpress注释链接和注释编号在href上

Question

I tried the search but did not get the complete answer to my question. I build a WordPress website with redux framework options panel and need switch on/off the option to hide meta info on WordPress posts.

I got already post date&author post link working but have a problem with echo href on WordPress comments link.

original code looks like this

<i class="far fa-comment"></i>&nbsp;<a href="<?php comments_link(); ?>"><?php comments_number('No comments', '1 comment', '% comments'); ?></a>

but I need to echo it inside PHP code

<?php global $wpdf;
if( $wpdf['text-muted']){
    //Do Something if switch is on(i.e - true)
    if(esc_html($wpdf['text-muted'] == '1')) { 
        echo '<i class="far fa-calendar-alt"></i>&nbsp;';
        echo wpdf_post_date();
        echo '&nbsp;|&nbsp;<i class="far fa-user"></i>&nbsp;';
        echo the_author_posts_link();
        echo '&nbsp;|&nbsp;<i class="far fa-comment"></i>&nbsp;';
    }
}
?>

Answer 1

It should be like this:

echo '<i class="far fa-comment"></i>&nbsp;<a href="'.get_comments_link( $post_ID ).'">'.comments_number("No comments", "1 comment", "% comments").'</a>';
